BOSTON, MA, January 21, 2003 — PAREXEL International Corporation (Nasdaq:PRXL) today announced the signing of a definitive agreement to acquire FW Pharma Systems Ltd., a leading software company that delivers enterprise-wide clinical trial management systems (CTMS). The privately held company is based in Birmingham, United Kingdom. Following the closing of the acquisition, FW Pharma Systems Ltd. will be combined with the operations of Perceptive Informatics, Inc. (Perceptive), the information technology subsidiary of PAREXEL.

The transaction will be financed through a combination of cash and PAREXEL stock with a purchase price totaling as much as $15.4 million. Closing is subject to the satisfaction of certain conditions and is expected to take place early in the third quarter of Fiscal 2003 (which ends March 31, 2003). Further specifics of the deal were not disclosed.

The primary product of FW Pharma Systems is “IMPACT” which is used by eleven of the top twenty pharmaceutical companies, and has over 13,000 users worldwide. The product helps clients plan and monitor the progress of trials, track supplies and costs, and enter monitoring data remotely. A second product, known as “INITIATOR”, provides trial management capabilities that specifically address the needs of Phase I trials. The clients of FW Pharma Systems include pharmaceutical and biotechnology companies, as well as contract research organizations.

Josef H. von Rickenbach, PAREXEL’s Chairman and Chief Executive Officer stated, “The products of FW Pharma Systems strongly complement Perceptive’s existing portfolio.

FW Pharma Systems has a solid reputation for quality and a history of excellence, and we are extremely excited to be joining forces with them.”

Mark A. Goldberg, M.D., President of Perceptive stated, “The products of FW Pharma Systems, when combined with the power of Perceptive’s web-based portal systems, investigator database tools, and interactive voice response systems (IVRS), give us the ability to improve clinical trial management on an enterprise-wide basis. Our vendor neutral approach allows for the integration of our solutions with various third party and in-house systems. The expanded suite of products and services resulting from this acquisition will solidify Perceptive’s position as a market leader in technology that facilitates drug development.”

FW Pharma Systems employs approximately 80 individuals and has offices in Oxford, United Kingdom; Malvern, Pennsylvania; and San Mateo, California in addition to its headquarters in Birmingham.
